  • Understanding the gap between Efficiency and Comfort

    IEEE

    The evolution of efficient building systems coupled with better feedback through ubiquitous low-cost networked environmental sensors should provide the necessary ingredients for improved occupant comfort using less energy. The lack of this outcome highlights a gap between the ability to measure environmental conditions and the ability to control conditions effectively. We present a critical review of research on comfort and sensors combined with new actuator and controls theory, which results…

    The evolution of efficient building systems coupled with better feedback through ubiquitous low-cost networked environmental sensors should provide the necessary ingredients for improved occupant comfort using less energy. The lack of this outcome highlights a gap between the ability to measure environmental conditions and the ability to control conditions effectively. We present a critical review of research on comfort and sensors combined with new actuator and controls theory, which results in our proposal of a new paradigm for a more integrative and contemporary framework for building operation by fully leveraging new theory and modern hardware, software, and computational capacity.

  • Membrane-assisted radiant cooling for expanding thermal comfort zones globally without air conditioning

    PNAS

    In this paper, we present results from a radiant cooling pavilion, demonstrating a method of cooling people without cooling the air. Instead, surfaces are chilled, and thermal radiation is used to keep people cool. A thermally transparent membrane is used to prevent unwanted air cooling and condensation, a required precursor to deploying radiant cooling panels without humidity control in tropical environments. The results from this thermal-comfort study demonstrate the ability to keep people…

    In this paper, we present results from a radiant cooling pavilion, demonstrating a method of cooling people without cooling the air. Instead, surfaces are chilled, and thermal radiation is used to keep people cool. A thermally transparent membrane is used to prevent unwanted air cooling and condensation, a required precursor to deploying radiant cooling panels without humidity control in tropical environments. The results from this thermal-comfort study demonstrate the ability to keep people comfortable with radiation in warm air, a paradigm-shifting approach to thermal comfort that may help curb global cooling-demand projections.

  • Built Environment Ecosystems Framework towards Sustainable Urban Housing Infrastructure

    IOP Science

    As the rates of urbanization increase to unprecedented levels, the urgent need for sustainable housing and infrastructure has become a widespread global challenge with social, economic and ecological implications. The housing sector directly impacts the majority of the United Nations (UN) Sustainable Development Goals (SGDs). However, striving to achieve these goals in a compartmentalized or siloed manner has impeded the implementation of transformational solutions that increase the security…

    As the rates of urbanization increase to unprecedented levels, the urgent need for sustainable housing and infrastructure has become a widespread global challenge with social, economic and ecological implications. The housing sector directly impacts the majority of the United Nations (UN) Sustainable Development Goals (SGDs). However, striving to achieve these goals in a compartmentalized or siloed manner has impeded the implementation of transformational solutions that increase the security and wellbeing of urban populations. Here, we introduce the Built Environment Ecosystems (BEE) framework, alongside a case study from the Ecological Living Module (ELM) UNEP Program, through an integrated systems approach with synergistic impact. We demonstrate how the multifunctional interlinking of building systems that harness local bioclimatic resources (ie. solar, wind, water, food, agricultural waste, biomaterials) can more viably address a broad spectrum of sustainable development challenges, while increasing local stakeholder agency. We outline how the BEE framework enables the association of SDGs as an integrated package, with an ELM performing as a scalable but Self-reliant Ecosystem of Systems, that could enable systemic change, suggesting the need for further research towards a scale up in the density of such housing systems across multiple climatic and cultural contexts towards ubiquitous sustainable urban housing.

  • Generation and Simulation of Indoor Thermal Gradients: MRT for Asymmetric Radiant Heat Fluxes

    IBPSA

    The inherent geometric and material dependence of radiant heat transfer can be leveraged to improve system efficiency and thermal comfort. Unlike in air-based systems, non-uniform temperature distribution can be highly controlled and beneficial in radiant systems, where temperature perception can be manipulated locally. An experiment was devised with the aim of creating a significant temperature gradient in a single space by using radiant heat transfer to cool certain parts of a room while…

    The inherent geometric and material dependence of radiant heat transfer can be leveraged to improve system efficiency and thermal comfort. Unlike in air-based systems, non-uniform temperature distribution can be highly controlled and beneficial in radiant systems, where temperature perception can be manipulated locally. An experiment was devised with the aim of creating a significant temperature gradient in a single space by using radiant heat transfer to cool certain parts of a room while simultaneously heating other parts. This was achieved by inducing radiant fluxes from hot and cold emissive pipes and directing them at different areas of the room through the use of curved infrared reflective surfaces. A 3D simulation was created to analyze the consequences of such a configuration for the Mean Radiant Temperature (MRT). The simulation utilizes a ray-tracing technique to account for multiple reflection bounces. The results are compared to MRT measurements taken in the physical experiment using Black Globe Thermometers. A simulation study of the heat transfer characteristics of a single pipe in a parabolic trough is also discussed.

  • The Cold Tube, Singapore

    -

    “The Cold Tube” explores new applications of selected materials for radiant cooling in tropical climates. It involves studying the use of infrared-transparent membranes that allow one’s body to experience the cooling effect of actively chilled surfaces hidden behind these membranes. Yet, they are sufficiently separated from these surfaces to avoid the problems of condensation. The goal of the project is to demonstrate how this new energy-efficient technology might provide outdoor thermal…

  • Energy is Everywhere and Nowhere

    -

    Energy is an elusive concept. While being universally recognized it is rarely understood. We continually misinterpret our thermal interactions with the surroundings. We have curated interfaces that elucidate often overlooked aspects of energy - from the potentials of low exergy buildings to the misperceived heat transfer from surfaces around us - contextualized within a framework of energy opportunities that are literally everywhere, but nowhere to be seen. This exhibition reveals the…

    Energy is an elusive concept. While being universally recognized it is rarely understood. We continually misinterpret our thermal interactions with the surroundings. We have curated interfaces that elucidate often overlooked aspects of energy - from the potentials of low exergy buildings to the misperceived heat transfer from surfaces around us - contextualized within a framework of energy opportunities that are literally everywhere, but nowhere to be seen. This exhibition reveals the manifestations of energy by unexpected means at three radically different scales: the human body, the building scale, and the urban scale. The various projects displayed explore the transfer of thermal energy which connects all three into an interdependent network of exchange.

  • DC Mini Maker Faire

    -

    Located in our Nation’s Capital, and following in the footsteps of recent area Mini Maker Faires (the Silver Spring and Northern Virginia Mini Maker Faires, respectively), the DC Community Mini Maker Faire was envisioned as a way to Show (and Tell) the world what a diversity of Washington DC makers have to offer the world.

    By projecting structured light at a 3D object, a webcam can capture how the light morphs & wraps around the object. With some clever programming, we are able to create a 3D point cloud, which is just a few steps away from being modified into an STL file for 3D printing.
